LUBRICATING DEVICE.

To all whom it may concern Be it known that I, ISAAC H. Srsson, a

' citizen-of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented cering devices adapted more especially for use.

.nism. Means connected with the float serves to visually indicate whether the small containers chamber is filled with the oil or is empty. The total cubical capacity of the chamber, minus the volume displaced by the float itself, equals the amount of oil constituting onecharge, or pre-measured quantity.

it may be stated that it is found desirable to lubricate the engine and mechanism of the self-propelled vehicle with a predetermined charge-0r quantity of oil while it is traveling a certain number of miles, as for example, fifty. By means of my invention uniform charges of the oil may be fed to the motor as desired, first noting, however, in each instance, that the small container is filled with the oil before it is permitted to determining the capacity and frequency of nism, respectively.

the charges. By means of the invention: the driver can readily ascertain through the medium of the indicator or tell-tale Whether the pipe connections, &c., communicating with the main supply of lubricating-oil, small container and the motor mechanism are normally working.

The charge-holding or small container is provided with a freely vertically movable float of known displacement. The container is also provided with intake anddischarge connections communicating with the main supply tank and the motor mecha- A manually controlled self-seating apertured valve having a stem extending upward through the small 'container to a convenient height and terminating in a handle member afford means through which the valve movements may be efi'ected. The float member is or may be fixed to a light, tubular indicator member and inclosing the valve-stem; the upper portion of the tube being visible through a glass-covered protected opening formed in the wall of an outer stationary tube extendin upward concentric to said indicator and va ve-stem members.

Inv the accompanying sheet of drawings illustrating my improved lubricating device, Figure 1 represents a partial longitudinal sectional view of a portion of a motor-vehicle, showing the seat, dash, etc., and the relative arrangement of the lubricating mechanism thereto. Fig. 2 represents, in enlarged scale, a vertical sectional view, taken substantially through the center of the float-carrying sub-holder or small container, the intake passage being open to. the chamber. Fig. 3 is a. corresponding horizontal sectional view, taken on line 3'3 of Fig.

2. Fig. i is a similar sectional view, showing the valve in open communicationwith the discharge or outflow passage. Fig. 5 is a horizontal sectional view, the valve itself being omitted; and Fig. 6 is a front elevation, in partial section, showing the upper portion of the valve-stem, movable indicator tube or tell-tale and the stationary outer tube, the vposition cf the parts corresponding with Fig. 2 e chamber assumed to be filled with the The following a sc ibes more in detail the construction of ice and manner of its operation:

i'n i termined capacity, say one pint. Its outerside walls a terminate in an integral base portion a having independent passages 12, 6 extending through the faced valve-seat '0 formed in'the bottom of said chamber. An angularly movable valve '0 is superimposed upon said seat, a packing element '0 being fixed to the valve and bearing against the seat 11 for obvious purposes. A single port or hole It extends vertically through the valve and its packing and is arranged to" register with the passages b, b. In order to centralize and support the valve, the latter may be provided with a hub 21 fitting a re-- cessed. opening '0' formed in the seat '0 The valve is kept normally seated by means of a helical spring 8 pressing againstit and a stationary bar 77, the latter secured to studs 6. To the valve is fixed a valve-stem m extending upwardlythrough, the top a of the container and surmounted by a valvecontrolling handle m Within the said chamber 0 is mounted a vertically movable float F of suitable material or,-substance; said float is secured to a central vertical tube. f or tell-tale, .through which the valvestem freely extends; the "volume or dis-- placement of the float beingequal say to that of a half-pint of lubricating-oil, or other quantity, as desired. An outer float-pro tecting tube 11. is fixed to the oil-tight cover a and extends upwardly therefrom, its top end being supported in the counterborea of bracket a secured to the dash. The said movable tube f of the float extends upwardly within the outer tube 12., its upper end being flush with that'of tube n when the chamber C is fully charged with lubricating oil. Fig. 6 shows the corresponding position of the indicator when the chamber is thus filled. In order to limit the upward movement of the float, the end of the indicator-tube f of the latter may engage the bottom of said counterbore, thereby automatically positioning the float itself a distance below the upper end of chamber C and correspondinglyreducing the indicator 's movement. It will be observed that .-in charging the chamber, the inflowing oil under suflicient head is adapted to pass under,

, around and over the float until the chamber is filled, the buoyancy of the float keeping the indicator in the said upper position until the release of oil from the chamber takes place. i The distance E, Fig. 6,-f1'om the upper end of the indicator 7, when elevated to its limit of movement, down to the upper edge 0 of an elongated visual opening 0 formed in the wall of the stationary outer tube 01. is or may be just equalto the length of the opening 0, which also corresponds to the distance the float falls while the oil in chamber G is being discharged therefrom.

The upper portion 70 of the indicator may be ainted some prominent, distinctive color di erent from that of the other part, thereby denoting that the chamber C is filled with oil when the'part k is concealed or invisible, said part moving downward with the float and registering with the visual opening 0 when the chamber is empty. The length of part 70 may equal the distance 7:.

In Fig. .3 the valve is shown positioned to receive oil from the reservoir B, via pipe 2', port I), and valve opening it, direct into the charging chamber C; the pin p of the valve then engaging the stationary bar 72 and limiting the valves movementin that direction. In order to empty the chamber the valve is rotated in the opposite. direction (see arrow as Fig. 3) until its opening h registers with the port I), the stop-ping; then engaging the opposite edge portion of the bar -,vsee Fig.'4=; the outflowing charge of oil immediately passes from the chamber C, via the port I) and pipe 5 into the motor, &c., as before stated. When the indicator shows that the chamber is empty, the float has fallen to its lowest position and rests on the fixed bar 70; theoperator may now recharge the chamber with oil by simply reversing the movement of the valve; the re- 1 filled chamber remains in this condition until the next succeeding release of the oil takes place, as determined by the judgment of the operator.

While the foregoing describes the construction and arrangement of the parts represented in the drawings, it is obvious that elements of the same general character may be employed without departing from the spirit and scope of the invention.

I claim a 1. In a lubricatin appliance .for a motorvehicle, a major tan or container for bold: ing lubricating-oil, a suitably located minor container having a chamber of pred'etermined capacity, inlet and ,outlet connections for conducting oil from the major tank to the minor container and for leading it therefrom to an element to lie lubricated, a manually controlled valve movably mounted 1 in said chamber constructed to register with said inlet and outlet openings, a buoyant float-member having limited vertical movement inclosed in the chamber'and-disposed above said valve, and means for visually in- .130
